5. Market share / trading volume

  • Trading volume: bitbank displays an attributed No. 1 domestic altcoin trading-volume claim limited to its own analysis for November 2024 through October 2025. This entry does not restate the comparison value without the calculation period and JVCEA-data context.
  • Number of accounts: Not disclosed
  • Customer base: Centered on retail (individual investors). Corporate services are also offered.
  • Competitive positioning: no permanent ranking or relative volume against peers is asserted. For an industry comparison of spot trading volume, see JVCEA Domestic Spot Trading Volume Statistical Analysis (2017-2026).

6. History / major events

This table is limited to verifiable corporate and regulatory milestones.
